The preparation of graphene, mono-, bi- and multi-layers from graphite-based precursor materials, for example, pencil lead or graphite, by a method of mechanical thinning on the surface of a planar substrate with controlled roughness, followed by sonication in order to collect the graphene deposited on the substrate in a liquid medium. The bearing force during thinning by mechanical friction enables the number of graphene sheets deposited on the surface of the substrate to be controlled.

The invention relates to a chemical reactor with a nanometric superstructure, comprising at least one member wherein at least one reaction chamber is arranged, and said reaction chamber being filled at least partially with a high specific surface area material having a specific surface area greater than 5 m/g, and characterized in that said high specific surface area material is selected from nanotubes or nanofibers. These nanotubes or nanofibers are preferably selected in the group consisting of carbon nanofibers or nanotubes, &#x3b2;-SiC nanofibers or nanotubes, TiOnanofibers or nanotubes. They may be deposited on an intermediate structure selected in the group consisting of glass fibers, carbon fibers, SiC foams, carbon foams, alveolar &#x3b2;-SiC foams, said intermediate structure filling the reaction chamber of said reactor at least partially.
